What is Margin in Forex? 

In forex trading, margin is the amount of capital a trader must deposit to open and maintain a leveraged position. It is not a fee but acts as collateral to cover potential losses. Margin is typically expressed as a percentage of the total trade size. For example, with 100:1 leverage, opening a $100,000 position would require a $1,000 margin deposit. This allows traders to control larger trades than their account balance alone would permit, but it also increases exposure to risk if the market moves against them.

What is Margin Level in Forex?

In forex trading, the margin level is the percentage that represents the ratio between a trader’s equity and used margin. It shows how much capital is currently available relative to the margin requirements.

How to Calculate Margin Level in Forex

Margin in forex is calculated as (Equity / Used Margin) * 100. For example, if a trader has $1,000 equity and $500 in used margin, their margin level is 200%.
